Has anyone ever emulated a PC with the Emplant?

486 OverDrive
486 OverDrive

Both are currently under 50 SEK (About 3£, 6€, 7$)...

That's the wrong king of chip though. Those are Intel Overdrive chips that allowed you to put up to a 200MHz MMX "Pentium" chip in your 486 (AMD made a similar chip that went up to 233MHz MMX but was flakey). What you'd need for a BridgeBoard would be a 386 Overdrive chip.

No, look at the chips. Those are 486 CPUs designed to fit in 386-sockets.

TOUCHE' Whabang!!

Well, the image is all pretty and everything...  But, a DPR20DX66 is not a 386 form factor. It's a 486 form factor.

Look at the top and then Look at the bottom

This is what the form factor looks like for a 386 chip (bottom view of a Cyrix overdrive chip). It doesn't have pins/legs. It's more of a PLCC type of socket. You can instantly tell if a cpu is a 386 from the top because it has "fuzzy" sides.

And before anyone hollers "but some 386's have pins!" you're right - 386 DX chips have pins, but they don't have 17 across they have 14.

Of course... if you really want to see photos of what cpu is what, I recommend the CPU Museum for some superb pictures.


I think a Touche retraction is in order thanks. :lol:

Bloody hell! :-x
That's what one gets for not counting pins! :lol:

Anyway. I know about CPU-museum it's a great site. THIS is the CPU it thought it was BTW. I haven't seen one of those for years. :-D

Funny fact: Cyrix's 486s were identical to their 386s, except for the larger cache.
